Here is an example of my mindset when I shop.This is from September so the seasonal items are not on sale in April-- but it gives you the idea.
I went to safeway because I needed cheese for tonight's (Friday) dinner. I checked my ad list and saw that cheese was on sale. I also noticed from my list that fresh corn was on sale this week (6 ears for $1), and organic plums were $1.99 a pound. On a Friday Only sale was Heinz ketchup in a 30 oz. container (The kind with no HFCS). So yesterday when I was looking to see where cheese was on sale I decided to go on Friday so I could take advantage of the ketchup sale too. While I was at Safeway I checked all the usual clearance spots and found organic soy sauce, organic tamari and rice vinegar on clearance. I stocked up on those items because they meet all my stock up criteria. (Good quality food, food that we will eventually use, non-perishable food, food that I normally would buy) The eggs were $1.52 which is more than I will normally pay for them ( I try for under a dollar), but since I filled out Safeways online registration for coupons I got them for free. In addition I also got a coupon that printed out because I purchased kikkoman sauces for $2.00 off our next shopping trip. I am kicking myself because I had a coupon for 20% off of Safeway produce so I could have saved that had I remembered my coupon so I may bring the coupon and reciept with me soon, get more of the kikkoman sauces if they are still on sale ( see if another coupon prints out) and really clean up!
What I got: What I paid for it:
3 jars of ketchup $1.49 each $4.47
3 kikkoman organic soy sauce $1.69 each $5.07
2 kikkoman tamari sauce (also organic) $1.39 each $2.78
3 kikkoman rice vinegar $0.92 each $2.76
1 dozen eggs FREE
1 2 pound bag of shredded cheese $5.99
6 ears of corn (6 for $1) $1
organic black plums ($1.99 a pound) $4.84
Total Charged $26.92
*$2.00 off next trip to Safeway
So now that you've seen my example of a shopping trip let me explain it a bit. It's a great example of eating according to what is in season (stone fruit and corn on the cob), cherry picking (buying only the sale items -eggs, produce, ketchup, and not getting lured in by other things (baked goods, convenience foods)). And stocking up when prices are good (kikkoman sauces, and the ketchup).
